Something that might be worth looking at for this is the debug.[ch]  
files in the Zoom source, which contains the code for reading I6 debug  
files, amongst other things. With this, implementing this should be a  
matter of hijacking the call instruction and looking up which function  
the address belongs to. You'd need to remove a lot of stuff that  
depends on other parts of Zoom, but I think the symbol reader itself  
should be pretty independent.
